Parallel Capacitor

Capacitors can run over a long time under working current no greater than 1.3 times of the capacitor rated current., caused by increased voltage and uppper harmonic waves.

Capacitors can run over a long time under working voltages, maximum of which is no greater than 1.1 times of the caacitor rated voltage.  

(3)hihg voltage film paralleling capacitor: no greater than 0.0005.

(2)high voltage film and paper capacitor: no greater than 0.0012;

(1)low voltage film and paper capacitor: no greater than 0.0022;

At the rated line-frequency voltage, the consumptive angle tangent value of capacitors at 20 centidegree:

Capacitance tolerance for capacitors should be within the range of -5% - +10% of the rated value.

Installation conditions: -40 - + 45 under general cimatic conditions; allowed altitude: no greater than 2000m for low voltage capacitors and no greater than 1000m for high voltage capacitors.

Hihg voltage paralleling capacitors with rated voltage higher than 1000V are in strict accordance with national standard GB/T11024,1-2001, which is equivalent to the international standard IEC60871-1:1997).

Low voltage paralleling capacitors, with rated voltage at or less than 1000 V, are in strict accordance with national standard GB3983,1-89.
